Implement ignoreRequest for input:select

This is something that could be useful for all of the tags in the input 
library probably. Is ignoreRequest the best way to achieve it or could we have 
something like a "value" attribute which behaves like default but cancels the 
behaviour of looking in a request and in the bean (if provided). What are your 
thoughts?

I think it could be useful for any tag that provides behavior besides the
automatic fill-in of the value from the request.  Otherwise, you could just use
the HTML.  

For example:  the reason why I use input:select it that it lets me specify the
options as a Map and specify which one of them is selected.  input:text, on the
other hand, doesn't seem to have anything going for it over pure HTML, except
for the fact that it will take a value out of the request and use it as its
value.  If you added an ignoreRequest attribute, you might as well have just
done <input type="text" ... />.

Also: It seems to me that if you don't want to use the bean attribute, you could
just omit it.  However, I haven't used the input taglib that much so I could be
missing something.

It is a useful feature. The text box is still useful even if you don't use the 
request as it will perform all of the necessary character escaping etc for 
your values.

Now all I'm considering is whether to call the attribute ignoreRequest or 
useRequest - with a default of true. I'm going to have a look at other taglibs 
to see if there's a defacto standard

I have just committed a solution to this. I have added value/selectedValue(s)/checkedValue(s) to all of the 
input tags. This can be used instead of default(s) to specify an actual value to use rather than a default 
that can be overridden. I chose "value" rather than "ignoreRequest" as it is closer to the actual "value" 
attribute in the HTML input tag.
